Egyptian grid code of wind farms and power quality

Abstract

Compliance with interconnection requirements is mandatory for grid interconnected wind farms. However, there are many barriers on the track. Diversity, ambiguity, consecutive drafts and updated codes, and the different sets of connection requirements are some of these obstacles. This chapter demonstrates the recent challenges concerning the wind farms-grid interconnection regulations. The general values and impacts for wind farms-grid interconnection are presented based on the recently published Egyptian grid code. The authorities and responsibilities of the grid operators, conditions of the connection, reconnection and disconnection of farms, active and reactive power control are introduced and discussed. Besides, the various requirements concerning with quality of power (especially in weak grids), such as flickers, harmonics, imbalance and voltage fluctuations are discussed in details.
